Abstract: An airbag assembly may include an airbag and an inflator that provides inflation gas to inflate the airbag. A filter module may be positioned such that inflation gas exiting the inflator must first pass through the filter module. The filter module may be formed of a sheet of metal that is wrapped into a generally spiraling tubular shape. The filter module may have an inner layer, an intermediate layer, and an outer layer. The intermediate layer generally encircles the inner layer, and the outer layer generally encircles the inner layer and the intermediate layer in a spiraling fashion. The inner layer, the intermediate layer, and the outer layer each may have a pattern of holes and dimples that are separate from and/or displaced from each other. The dimples may protrude toward an adjacent layer to maintain spacing to enable relatively unrestricted gas flow from the holes of the inner layer through unaligned holes of the intermediate layer and the outer layer.

Abstract: Expanded metal sheets are used to produce tubular filters. The expanded metal sheet has a multiplicity of rows of openings arranged to reduce nesting when the sheet is rolled on itself. In particular, the pitch between the rows of openings, the sizes of the openings, or both the pitch between the rows of openings and the sizes of the openings are varied to reduce nesting when the expanded metal sheet is rolled on itself. The filters can include external circumferential grooves, rounded corners produced by a point loading process, textured surfaces between openings, and/or torturous internal paths produced by non-perforated areas of an expanded metal sheet. The expanded metal sheet can be composed of carbon steel coated with a material having a higher heat conductivity, e.g., tin. Among other things, the filters can be used in automobile airbag inflators to capture slag and absorb heat produced by the inflator's explosive charge.

Abstract: The present invention relates to a foil trap device for debris mitigation, in particular in an EUV system. The foil trap comprises a plurality of spaced apart foils (4) extending from an entrance side towards an exit side of the foil trap, said foils (4) being arranged to allow a straight pass of radiation between the entrance side and the exit side. The foils (4) are coated at least at entrance side edges with a layer (8, 11) of a carbon material containing a fraction of at least 60% of sp3-hybridized carbon atoms, or with a layer (8, 11) of carbon nanotubes. As an alternative, the foils (4) are made of a bulk carbon material of the above composition. The proposed foil trap offers the combination of a high thermal conductivity, a high thermo-chemical resistance against Sn and other liquid metals and a high mechanical stiffness.

Abstract: The invention relates to a lamellar separator for separating liquid droplets from a liquid-charged fluid, having at least two essentially vertically oriented lamellar profiles, which are spaced apart from one another, and which form a flow channel between them for conducting through the liquid-charged fluid and on the wall surfaces of which the liquid droplets are separated, and having a catch basin situated below the lamellar profiles for receiving the liquid separated from the liquid-charged fluid, the catch basin having at least one partition wall, which divides the catch basin into multiple areas.

Abstract: A low-profile vapor-liquid separator, such as a steam-water separator is described having an inlet opening for receiving a flow of a vapor-liquid mixture and an outlet opening for exhausting the flow of a vapor-liquid mixture after removal of the liquid. A passageway that extending longitudinally between the inlet opening and the outlet opening has a plurality of spinner blades that rotate the liquid to a slot in the wall for removal. The separator has an unobstructed passageway with few slots that increases rotation and centrifugal separation. Due to its efficiency it may be made much smaller than predecessor separators.

Abstract: The invention concerns a flow turning vane assembly for use in a duct bend portion of a clean air duct of an air induction system for a vehicle engine. The flow turning vane assembly may have a vane support housing, and a hydrocarbon adsorbent vane mounted to the vane support housing. The hydrocarbon adsorbent vane has a curved shape complimentary to the duct bend portion and includes a hydrocarbon adsorbent layer.

Abstract: A vapor-liquid separator, such as a steam-water separator that is suitable for use in the drum of a steam boiler, including a chamber having an inlet opening for receiving a flow of a vapor-liquid mixture and an outlet opening for exhausting the flow of a vapor-liquid mixture after the vapor-liquid mixture has been subjected to the removal of droplets of liquid therefrom. A chamber is provided with a wall having an inner surface that is operative to define a passageway that extends longitudinally between the inlet opening and the outlet opening. A slot is suitably formed so as to pass through the inner surface and the outer surface of the wall of the chamber. A plurality of spinner blades is suitably disposed within the passageway so as to be positioned below the slot.

Abstract: An edge filter assembly is disclosed. The edge filter assembly may include a housing having an inlet and an outlet. The edge filter assembly may further include a filter element disposed within the housing including first and second filter plates and first and second spacers disposed between the first and second filter plates. The spacers and filter plates may be configured and arranged to form a flow channel extending generally radially within the housing and defined between the first and second filter plates and the first and second spacers. The flow channel may have an inner flow gate and an outer flow gate. The inner flow gate may be disposed radially inward of the outer flow gate and may have a different cross-sectional configuration than the outer flow gate. The first filter plate may have an axial projection extending therefrom generally aligned with a fluid path within the housing.

Abstract: An apparatus into which particulate material contents of rupturable bags may be charged for further handling including a hopper having an inlet into which the material may be charged, producing portions of settling and airborne particles of the material, and an outlet through which the settling portion of the material may be discharged, a first filtering unit having an inlet communicating with the hopper inlet, a second filter unit having an inlet communicating with an outlet of the first filter unit and means for producing an air flow from the hopper inlet and sequentially through the first and second filter units whereby the portion of airborne particles of the material is drawn by the air stream through the filter units for removing the airborne particles therein.

Abstract: The present invention relates to an enhanced exclusion filter having a cylindrical stack of substantially identical annular disks and a central rotating element. Each annular disk engages the rotating element by at least one strut which extends inward from the inner perimeter of the annular disk toward the central axis of the cylindrical stack. Protuberances extend from the annular disks and engage depressions in adjacent annular disks to maintain the spacing between adjacent annular disks. Dimples extending through the annular disks may be utilized to form a depression on one surface of an annular disk and a protuberance on the opposite surface of the annular disk. The annular disks are angularly offset by a fixed amount from the adjacent annular disks so that rough vane surfaces are formed by the struts of the annular disks. Preferably a pattern of substantially identical angular offsets is used.
